The system includes a mode control assembly for selectively controlling the movement of said supply station for sheet or tractor media; a pair of guide wheels constructed and mounted for engagement with tractor media along a tractor media inlet passage; bail rollers engaging the platen between the print path ingress and egress; and a variable spring system for urging the bail rollers against the print platen with higher or lower nip pressures for sheet or tractor media conditions.
